摘要： A phenolic resin composition for fiber-reinforced composite material, comprising at least the following constituent A and thermoplastic resin B. A : phenolic resin, and B : at least one thermoplastic resin selected from among polyvinyl formal, polyvinyl acetal, polyvinyl butyral, polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol, polyethylene glycol, copolymer nylon, and dimer acid polyamide. A prepreg for fiber-reinforced composite material is produced by coating a film with the resin composition and impregnating the film with reinforcing fibers under heat and pressure.

摘要： A prepreg consisting of the following constituent elements: (A), (B) and (C), and the constituent element (C) is distributed in the portion of the prepreg which is close to a superficial layer of one or both surfaces thereof, the constituent element (C) not having regular arrangement (A) reinforced fibers consisting of long fibers; (B) matrix resin; (C) long fibers of a thermoplastic resin. The prepreg according to the present invention gives a composite material retaining its tacking characteristics and draping characteristics and its thermal resistance when it is hot formed, and having excellent impact resistance and inter-layer tenacity. This prepreg is manufactured easily, and has a high degree of freedom as a material.

摘要： An epoxy resin composition for fiber-reinforced composite materials which is a thermosetting resin composition which, upon 2-hour heating at 180°C, gives a cured article having a glass transition temperature Tg of 150°C or higher, wherein the rigidity, G'R, of the cured article in a rubber-state flat region of temperatures not lower than the Tg is 10 MPa or lower. Thus, a fiber-reinforced composite material is provided which is excellent in moist heat resistance and strength properties such as impact resistance, tensile strength, and compression strength. Also provided are a prepreg and a thermosetting resin composition excellent in peel strength with respect to adhesion to honeycomb cores.
